Multi-ingredient stirring and mixing device with silencing and damping functions for bioengineering

Abstract

The invention discloses a multi-ingredient stirring and mixing device with silencing and damping functions for bioengineering. The device comprises a stirring tank and an upper cover, the upper coveris connected with the stirring tank through a buckle; a first feeding hole and a second feeding hole which are communicated with the interior of the stirring tank are respectively formed in the uppercover; the bottom of the stirring tank is connected with a material guide pipe provided with a ball valve. The device also comprises a pneumatic driver which is installed on the central axis in the stirring tank in the vertical direction and is in a round rod shape, and a stirring assembly and a driving box which are connected to the circumferential surface of the pneumatic driver in a sleeving mode. The driving box is in driving connection with the stirring assembly. The pneumatic driver is used for replacing the traditional motor drive, the stirring assembly is driven by the pneumatic driverto vertically move up and down in the stirring tank, vibration of the whole device is reduced, the motor for driving the stirring assembly is installed in the driving box in a sealed mode, the driving box is installed in the stirring tank, and noise is isolated through sound insulation and sound absorption materials filling in the inner wall of the stirring tank.

Description

technical field [0001] The invention relates to the field of mechanical stirring equipment, in particular to a multi-ingredient stirring and mixing device for bioengineering with the function of noise reduction and shock absorption. Background technique [0002] Bioengineering is based on the theory and technology of biology, combined with modern engineering technologies such as chemical engineering, machinery, and electronic computers, to modify organisms or their functions in a targeted manner, and then treat such "engineering bacteria" or "engineering bacteria" through appropriate bioreactors. Cell lines" are cultivated on a large scale to produce large amounts of useful metabolites. Many bioreactors will be used in this process, and in the early stage of biological cultivation, a stirring mixer is needed to mix and stir the raw materials. The current mixing and stirring device uses a stirring rod with stirring blades to rotate in the mixing drum , Stir and mix two or mo...

Problems solved by technology

Many bioreactors will be used in this process, and in the early stage of biological cultivation, a stirring mixer is needed to mix and stir the raw materials. The current mixing and stirring device uses a stirring rod with stirring blades to rotate in the mixing drum , Stir and mix two or more materials to make it into a mixture. The power to drive the stirring rod is a motor. The motor is installed outside the upper cover of the mixing drum, and the output shaft of the motor extends to the inside of the mixing drum to drive the stirring rod. Rotate to stir the raw materials, because the motor will vibrate when it is running at high speed, the vibration will not only affect the service life of the entire mixing device, but also generate noise due to the vibration, which will affect the working environment of the factory building and the health of workers. Based on this, this The invention proposes a multi-ingredient stirring and mixing device for bioengineering with the function of noise reduction and shock absorption
